Smoke and heat vents are often required
Smoke vents and smoke and heat ventilation systems are required by countries’ building regulations, fire safety and prevention designs, insurance companies and building permits. Smoke vents are installed in stairwells. Smoke and heat ventilation systems are required in buildings that call for a low-smoke layer if there is a fire. These include industrial buildings with production or storage facilities. They prevent hazardous gases from accumulating, rooms from becoming too hot and fires from spreading. Smoke and heat ventilation systems help people evacuate. These systems also assist in firefighting and rescue work.
Performing the calculations for and deciding on the smoke and heat ventilation system
The deciding factor is the surface area of the roof, windows and facade. This information is ascertained by the fitter using geometric and aerodynamic parameters, room height and the required low-smoke layer. In this case, the applicable standards include DIN 18232 and DIN EN 12101. To ensure the smoke vent openings are large enough and the smoke and heat ventilation system operates as intended, a large number of influencing factors are taken into consideration in the calculation. We here at CWS Fire Safety have the right experts for such tasks with our fire safety and prevention experts and expert engineers.

Installation and approval of smoke vents
CWS installs smoke and heat ventilation systems with custom-fit ventilation openings. Installation includes all elements: We install the control unit, trigger, opening units, pipe system and backup power supply system for you. We also install the smoke and heat ventilation system in conjunction with other fire safety and prevention equipment, such as fire alarms or sprinkler systems. Our fire safety and prevention experts will take care of everything and work closely with electrical, IT and other industry professionals. We will also take care of everything required to receive approval from the inspection.
Smoke vent maintenance and inspections
After receiving approval, we will set up regular maintenance and inspections. Smoke and heat ventilation systems must undergo yearly maintenance in accordance with DIN 18232 and VdS/CEA-Richtlinie 4020. We recommend more frequent maintenance for facilities exposed to dust and dirt. In accordance with PrüfVO, smoke and heat ventilation systems are required to undergo inspections every three to six years by a recognised inspector, depending on the federal state. This is generally not necessary for smoke vents in stairwells, unless it is directly required. To ensure proper operation, we inspect the trigger, control unit, openings, power supply lines and equipment to check their functionality and operational readiness. We will immediately send you the official documentation digitally.
